1991 Other Nissan Models Overheating :( Please Help

Engine Mechanical problem
1991 Other Nissan Models Front Wheel Drive Automatic 198000 miles

Hello,

Ive had this nissian 1991 bluebird SEsaloon for the last 5k kilometers and latley i have stoped driving it very far (have to take time of work) becuase of this problem

After driving for about ten minutes the temp gauge creeps past the halfway point and something does not smell right

Not long after a hissing sound occurs and white/ smoke steam comes out from under the hood

I have taken a picture with a arrow where the smoke/ steam is coming from.

I have been topping up the coolant as it has been burning threw it, but topped it up yesterday and went for a 10min drive and still at the same level

A couple of days ago just before this problem happend i heard scraping sound a few times sounded like something was dragging under the car but nothing was there.

There is some white flakey stuff around by where the coolent tank is (pic attached) that was not there before this happnd

I hear liquid boiling after driving as well

Is not burning threw oil

So guttered this had to happen just before xmas and any help would be greatly appreciated!!

Thanks
Robert
